Subheading show up in archive page

Hey, I tried to let the subheading show up in archive page,
websitepage where i would like it to show up.
It says it should automatically show up, but i cant figure out why it doesn’t in my theme.
I tried to understand and apply all the documentation, but my knowledge of php is limited.
Any help would be greatly appreciated.

this is the coding of the archive page:

<?php get_header(); ?>
	<?php
		// Check and get Sidebar Class
		$sidebar = get_option(THEME_SHORT_NAME.'_search_archive_sidebar','no-sidebar');
		$sidebar_array = gdl_get_sidebar_size( $sidebar );
	?>
	<div class="page-wrapper archive-page <?php echo $sidebar_array['sidebar_class']; ?>">
		<?php
			$left_sidebar = get_option(THEME_SHORT_NAME.'_search_archive_left_sidebar');
			$right_sidebar = get_option(THEME_SHORT_NAME.'_search_archive_right_sidebar');		

		// print title
		if( is_category() || is_tax('portfolio-category') ){
			$title = __('Category','gdl_front_end');
		}else if( is_tag() || is_tax('portfolio-tag') ){
			$title = __('Tag','gdl_front_end');
		}else if( is_day() ){
			$title = __('Day','gdl_front_end');
		}else if( is_month() ){
			$title = __('Month','gdl_front_end');
		}else if( is_year() ){
			$title = __('Year','gdl_front_end');
		}else if( is_author() ){
			$title = __('By','gdl_front_end');
		}		

		if(is_category() || is_tag() || is_tax('portfolio-category') || is_tax('portfolio-tag') ){
			$caption = single_cat_title('', false);
		}else if( is_day() ){
			$caption = get_the_date('F j, Y');
		}else if( is_month() ){
			$caption = get_the_date('F Y');
		}else if( is_year() ){
			$caption = get_the_date('Y');
		}else if( is_author() ){
			$author_id = get_query_var('author');
			$author = get_user_by('id', $author_id);
			$caption = $author->display_name;
		}
		print_page_header($title, $caption);	

			echo '<div class="row gdl-page-row-wrapper">';
			echo '<div class="gdl-page-left mb0 ' . $sidebar_array['page_left_class'] . '">';

			echo '<div class="row">';
			echo '<div class="gdl-page-item mb0 pb20 ' . $sidebar_array['page_item_class'] . '">';

			if( !is_tax('portfolio-category') && !is_tax('portfolio-tag') ){

				$item_class = $blog_div_size_num_class[$item_type]['class'];
				$item_size = $blog_div_size_num_class[$item_type][$sidebar_type];		

				echo '<div id="blog-item-holder" class="blog-item-holder">';
				if( $item_type == '1/4 Blog Widget' || $item_type == '1/3 Blog Widget' ||
					$item_type == '1/2 Blog Widget' || $item_type == '1/1 Blog Widget'){
					print_blog_widget($item_class, $item_size, $num_excerpt, $full_content, $item_type);
				}else if( $item_type == '1/1 Medium Thumbnail' ){
					print_blog_medium($item_class, $item_size, $num_excerpt, $full_content);
				}else if( $item_type == '1/1 Full Thumbnail' ){

				echo '</div>'; // blog-item-holder
			}else{

				$show_title = (get_option(THEME_SHORT_NAME.'_portfolio_archive_show_title' ,'Yes') == "Yes")? true: false;
				$show_tag = (get_option(THEME_SHORT_NAME.'_portfolio_archive_show_tags' ,'Yes') == "Yes")? true: false;
				print_normal_portfolio($port_size, $show_title, $show_tag);
			}

			echo '<div class="clear"></div>';
			pagination();

			echo "</div>"; // end of gdl-page-item

			get_sidebar('left');
			echo '<div class="clear"></div>';
			echo "</div>"; // row

			get_sidebar('right');
			echo '<div class="clear"></div>';
